Nest.JS部署到Heroku
我目前正在尝试部署Nest.JS CLI生成的基本入门模板(从5.3.0版开始),并且似乎在应用启动时获得超时。我想知道是否有人设法部署到Heroku?
我不确定我是否需要包含某种Procfile?
此外,似乎没有太多关于部署Nest.JS的信息
当我尝试部署时,Heroku会记录。

如果有人有部署这个堆栈的经验,那么很高兴收到你的来信
回答如下:Heroku默认为您指定一个端口并将端口添加到环境变量(env),因此您可以将端口设置为固定数字,您需要将主文件更改为:
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
async function bootstrap() {
const app = await NestFactory.create(AppModule);
await app.listen(process.env.PORT || 3000);
}
bootstrap();
